It seems my cb is coming through my
am/fm radio when it's off. It's a stock radio
and the tip of my antenna is about 50 feet off
the ground. I am using rg-8 coax.
My question is do they make some
kind of filter to help prevent this.

Make sure you have good grounds on both. A low pass filter might not
hurt, but I'm not sure if it will help either. Swr looks good?
